信息论是由通信技术、概率论、随机过程和数理统计等相结合逐步发展而形成的一门新兴科学。其奠基人是美国数学家香农，他的《通信的数学原理》奠定了信息论的基础。 这是信息论与编码技术的教学课件。压缩包内含有6个ppt文件，每个ppt自成一章:1绪论、2信源及其熵、3信道及其容量、4信息率失真函数、5信源编码、6信道编码。是初学信息论的最好材料。-Information communication technology is, probability theory and mathematical statistics, stochastic processes, such as the combination formed by the progressive development of an emerging science. The founders of the United States Shannon mathematician, his " Mathematical Theory of Communication" has laid a foundation of information theory. This is the information theory and coding technology courseware. Compressed packet contains 6 ppt documents, each a separate chapter ppt: 1 Introduction, 2 source and its entropy, and its 3-channel capacity, information rate-distortion function 4, 5, source coding, channel coding 6. Information theory is the best learning materials.
